Thoughts about using ethanol-free gas

[Mr. B5]

My '70 RR 6 pack will arrive in about 2-3 weeks, and I'd like to know your thoughts on using ethanol-free gas.
I can buy regular ethanol gas with 93 octane, but the e-free only runs about 90.
Do you think it will make the car run better?

Interesting. Around here, the lower grades have ethanol, but several stations (like Chevron) are alcohol free for premium.

If you don't need the knock resistance of the extra octane, yes. Will it be noticeable? Prolly not.

no water, no sticky parts,.....use octane booster fuel additive

don't put that ethanol crap in...

Try running the non ethanol gas and if you don't have pinging then no problem. I really try to stay away from the ethanol gas in old cars. You don't know what kind of rubber fuel line was used on your RR and I have seen it deteriorate fuel line. Any idea on the engine specs on the RR? That would determine your octane needs. Great minds think alike Sonny!

IMO, run the lower grade without the ethanol if you have to make that choice. I run into the same scenario in my neck of the woods. Twice I filled up with ethanol 93 (not much of a choice). Car ran noticeably hotter and on a warmer day it even vapor locked (on the warmer day out of the two times). Had a hard time getting it started after shutdown (even with a return line). Run 91 octane, ethanol free...runs better/smoother, cooler and zero hard starting/vapor lock issues (even on days 10-15 degrees more hot than the hard starting episode w/ethanol). This is on a higher compression 512 Stroker, so your 440 might not be as sensitive to the ethanol garbage, but I would guess it would be similar. Just my 2 cents.

I was using non-ethanol 92 regularly until I had to start driving the car daily and it got too expensive. But since it doesn't sit dormant with the corn squeezins in it I haven't noticed and deterioration of rubber or soft metal parts...yet. Haven't had any excess heat issues with either one, but I like the smell of the burnt NE 92 alot more than the corny stuff.

My 2003 Dodge 2500, 5.7 Hemi, manufacture recommends no ethanol gas.

MY 1997 HD 1340cc Evo, manufacture recommends no ethenol gas.

My 2005 Chrysler 2.4 dohc, have been using 10% ethenol for 100,000+ miles. Replaced the head gasket this spring and noticed how this crap really worked on the top end parts. Head gasket, valves, the aluminum corrosion.

There was some talk of doing away with ethanol, then there was talk about making all gas ethanol. What has anyone else heard on this???

Haven't heard, but god I hope they don't go to all ethanol. Wreaks living havoc with big 2 strokes like snowmobiles, 4 wheelers and yard equipment.

Think about using aviation fuel. Here is a link to a posting about it.

I forgot to mention that when I do use the 10% ethanol junk I add a bottle of Lucas ethanol fighter. I'm not exactly sure what it does, but I don't think it can hurt and its only 2-3 bux per tankful.

I'm still puzzled to read about all the trouble you seem to have over in the US with Ethanol mixed fuel.
Here in Sweden and the surrounding countries the Ethanol mix is standard, and nobody seems to have any trouble with it. Myself I've never had any trouble with any mix in any engine.
In fact for a performance engine the Ethanol/E85 is THE fuel.

If your carburetor is set up for non-ethanol fuel, your engine will run lean when you start using an Ethanol-blend.

Save the corn for making whiskey and the trees for making toilet paper. These two things are needed. Alcohol in gas is not needed!!

I run the 10% ethanol in everything I own, chainsaws, lawnmowers, trucks, cars and high performance engines to 780 HP. The only trouble ever was when placing cars back into service from long periods of storage (7-10 years). Under those circumstances the ethanol would clean all the rust from the tank and steel lines and plug up one or two fuel filters. After the fuel filters quit plugging up, all the vehicles have run fine.

I have found that ethonal in small motors that get put up for much time be come problematic when they are oil mix. the alcohol and oil create a gummy mess in the tiny carbs and lead to rebuilds and such. I think in warmer areas this happens faster. I use an off the shelf pre mix now days "FUEL" all my small engines start on the second pull for years now.

With that said in a car again where you live might effect it more due to your clement. Cars parked for long periods I would avoid it.( like said before many rubber parts were not planned to sit in anything but gas) I have swapped back and forth and never noticed any real differences.

I've been putting 4oz. of Marvel Mystery Oil in every tank of E-10 for a long time. No problems so far. The only place around here that sells non-e gas anymore charges about $1 a gallon extra for it.
